    Introduce socket shutdown into connection type, used if a fork is active (#11376) · fac188b4

    Introduce socket `shutdown()` into connection type, and use it
    on normal socket if a fork is active. This allows us to close
    client connections when there are child processes sharing the
    file descriptors.
    
    Fixes #10077. The reason is that since the `fork()` child is holding
    the file descriptors, the `close` in `unlinkClient -> connClose`
    isn't sufficient. The client will not realize that the connection is
    disconnected until the child process ends.
    
    Let's try to be conservative and only use shutdown when the fork is active.
